Humidity in the Data Center: The Real Hard Drive Killer

Researchers at Rutgers University found that humidity, not heat, is the single greatest detriment to a hard disk drive’s lifespan in a recently published HDD reliability study. This revised understanding of the ideal conditions for prolonging HDD longevity has the potential to change how data centers manage environmental conditions. The study examined one million HDDs across nine data centers over a period of 18 months to four years for each center. HDD failure is by far the most common hardware failure type at data centers, being responsible for 76 to 95 percent of all component failures. Not only can HDD failures mean lost data, but they also can add up in costs to replace. Read More

Hard Drive Failure Rates: Seagate Faces a Class Action Lawsuit

A February 2016 class action lawsuit argues that one manufacturer is responsible for selling hard drives that failed at a rate substantially higher than the industry average. The lawsuit targets HDD manufacturer Seagate over a 3TB model, arguing that the replacement of failed drives with the same model was inadequate in fulfilling warranty obligations because the failure rates on the replacement drives were so high. The lawsuit cites information from cloud storage provider Backblaze which claims the 3TB Seagate Barracuda 7200.14 failed at a staggeringly high 43.1% annual rate. Within three years only 68% of the drives Backblaze installed were still operational. Read More
